Filed: 1992-03-31
Abstract: The invention concerns a method for the processing free-flowing materials, in particular filter dusts from the iron and steel industry and waste-incineration plants, as well as a device for carrying out the method. In order to ensure that the end product produced can be used again or can be stored under conditions in which the environment is not polluted, the method comprises the following steps:  the material is mixed in the dry state with a reducing agent; the mixture is passed into a metallurgical vessel through a bore in at least one hollow electrode which passes into slag contained in the vessel, the mixture thus being introduced on to the surface of the slag in the vessel and then conveyed into the melt by means of gas; heat is supplied during the reaction between the mixture and the slag; constituents of the mixture which evaporate are removed by suction at a level above that of the slag; constituents of the mixture which sink are tapped off with the melt and the other constituents of the mixture remain in the slag and are removed with the slag. The bore in the hollow electrode is connected to a device (50) for passing gaseous media in or out. The power supply (30) includes elements designed to maintain the current constant (36) and to control the electrical power (37).

Patent DE-4244106-A1 (DE)
Title: Electronic appts. theft prevention device
Inventor: RUDRICH HANS-PETER
IPC: G08B13/14
Filed: 1992-12-24
Abstract: The valve control circuit (2) includes a coded locking circuit to lock the operation mode of the control circuit (2) when a locking criterion is satisfied, particularly when the armature (8) current supply is interrupted. The circuit also releases the operating mode after a release code is input. Further security is provided by introducing a sensor which detects a change in the normal installation and/or movement. This can also be sensitive to changes in surrounding or operating conditions.A response to this sensor, e.g. when the length of the device varies or moves, causes the locking circuit to lock the operating mode. The locking circuit is formed such that the operating mode cannot be released without the input of the release code after it has been locked.

IPC: H04H20/88
Filed: 1993-02-05
Abstract: In a circuit arrangement for decoding a multiplex signal in a stereo broadcast receiver, the multiplex signal contains an aggregate signal (L + R) in the baseband, a subcarrier modulated by means of a difference signal (L - R), and a pilot signal with half the frequency of the subcarrier. The multiplex signal in digital form is multiplied in two phase angles shifted by 90@ with respect to one another by a reference carrier obtained from a sampled clock pulse generated in the broadcast receiver. The mixed signals produced by the multiplication are each multiplied by a correction signal to form corrected mixed signals. The corrected mixed signals are added and fed together with the aggregate signal to a matrix circuit for forming stereo audio signals (L, R). <IMAGE>

Title: Fitting or dental prosthesis to remaining stump
Inventor: GOEPPEL THOMAS
IPC: G02B27/60
Filed: 1993-05-04
Abstract: Dental prosthesis is fitted to a stump using an appts. which includes an optical groove grating and an illumination system for the repeated projection of the grating onto the stump. A camera photographs the lines of the projected grating. Between the grating and stump is an optical deflecting system which separates the illuminating beam and output beam paths. The camera is of the matrix type producing moire fringes.     Pref. includes an optical groove grating (13) which projects a beam of light (11) onto a dental stump (1). The beam is deflected by a double prism (16) with silvered faces (17,18) and a diaphragm (19). The latter pref. has two closely juxtaposed apertures (21,22). Aperture (21) permits passage of the illuminating beam (11), while aperture (22) permits passage of an observation beam (23). Lens (24) produces a groove pattern (26) on the stump corresponding to the optical grating. Thi sis photographed using a CCD camera (28). Pref. a series of photographs are taken with the grating sequentially displaced by a component perpendicular to the extension direction of its grooves. The displacement against the grating lines is by increments of 0.1-1 degrees. The grating may be moved either by a motor or magnetically, in the latter case by applying discrete different voltages. It is moved between limiting stops and normally is kept in a zero position by springs. Pref. the grating lines are optically oriented against the columns of the camera under an angle of 90 degrees.
